I just love, love, love the looks of these lights.  I purchased them to use at our "off-the-grid cabin in the woods" which we will arrive at later this month.  I purchased them to decorate the front gardens just off our screened fromt porch.  I would have rated them higher, however, I only have one at our permanent home just to try.  Well, the issue is, it gets dark here in Florida and the lights come on around 8:00pm.  By the time I retire to bed at 11:30pm it is already off.  I have set up one more to see if that lasts longer for tonight.  I hope that one lasts longer.  I just checked them.  The new one is on now.  The first one is not hardly working.  We did have rain this evening.  Maybe the solar collector has water on it or something causing a problem. Not sure and not happy with that one.  I will set up the rest of them tomorrow to check them all out.  I will get back to you in a couple of days.
